Inventor: GUNJI HIROYOSHI
IPC: G09F9/00
Filed: 1992-02-27
Abstract: PURPOSE:To stabilize the performance of a liquid crystal display device by using an aluminum alloy sheet, thereby suppressing the temp. rise of even the display device having a large light source output and decreasing the fluctuations in temp. distribution. CONSTITUTION:The thermal conductivity of the reflection plate itself is enhanced and the heat radiation by heat conduction is accelerated by using the aluminum alloy sheet 7 as a base material. An effect of eliminating the nonuniformity in temp. by rapidly dispersing the local temp. rise is then obtd. The whiteness on the surface of the reflection plate 5 is enhanced and the reflectivity at a spectral stereoscopic angle is increased by applying a white coating plate film 6 on the reflection surface of the aluminum alloy sheet 7. The reflected of the high brightness uniform over the wide display surface is thereby obtd. The rear surface is subjected to an anodic oxidation treatment to expose an anodized oxidation film 8 so that the heat in the back light is radiated by conduction and radiation from the rear surface. The anodized oxidation film 8 enable extremel increase in the surface area. In addition, this film has a thermal conductivity as high as 0.16 and is, therefore, enhanced in heat radiation effect.

IPC: G11C11/407
Filed: 1985-04-12
Abstract: PURPOSE:To attain high-speed operation and low power consumption at the time of battery backup by controlling operation/hang-up of a back bias voltage generating circuit on the circuit board corresponding to the state when a TTL signal is supplied/not supplied. CONSTITUTION:When the TTL signal is supplied and an inversed chip-selection signal CS becomes lower than a logical threshold voltage, the output of the CMOS inverter circuit IV3 of the back bias voltage generating circuit on the board becomes H. Then a NAND gate G opens and operates as an inverter circuit substantially so that an oscillation operation is conducted. And a back bias voltage for board Vbb is generated through inverters IV4 and IV5, a capacitor C and a diode type FETQ51 etc. to decrease the influence of the parasitic capacitance of the board and accordingly the dynamic type RAM operates with high speed. On the contrary, when the power supply of the TTL circuit is interrupted hence the TTL signal is not supplied, the operation is stopped similarly and the back bias voltage generating circuit does not consume current. As a result, the consumption at the time of battery backup is decreased and the battery life is extended.

Abstract: PURPOSE:To reduce circuit scale and to attain low cost by supervising only one end of a telephone connection so as to detect grounding in a power supply circuit supplying a talking current to a telephone set. CONSTITUTION:When the supply voltage is V0=-48V and the system is in normal operation, since the resistance is selected as r1=r2, a point C shows a voltage below -24V and the potential of a point D is equal to that of the point C.

If the point A is grounded, a comaprator circuit 11 comparing the potential at the point D with a reference potential V2 outputs zero V, a transistor (TR) Q3 is turned off to disconnect the route of point A-resistor r2-TR Q2 thereby stopping the power supply. The point C shows the potential of -24V X R3/(R4+R3), which is larger than -24V and equal to the potential at grounding before power supply stop. At the time of releasing the grounding, the potential at the point C reaches -24V or below and the comparator circuit 11 obtains the information of grounding release.

Abstract: PURPOSE:To improve the fuel efficiency of an engine and reduce the size and weight of auxiliary machinery, by connecting the crankshaft of the engine to a driven shaft through a transmission mechanism to drive the plural auxiliary machines through a transmission unit provided on the driven shaft. CONSTITUTION:The torque of the crankshaft 1 of an engine is transmitted to a driven shaft 21 through a transmission mechanism comprising pulley assemblies 10, 20 and a belt 40. A plurality of auxiliary machines 32, 33, 34 are driven through the driven shaft 21 and a transmission unit 30. When the rotational frequency of the engine is in a low range, the rotation of the crankshaft 1 is transmitted to the driven shaft 21 at a prscribed speed reduction ratio. When the rotational frequency of the engine has become high, the distance between the V-belt 40 and the axis is changed by the centrifugal force of a weight 25 to keep the prescribed speed reduction ratio. The auxiliary machins 32, 33, 34 are thus driven at an appropriate transmission ratio. For that reason, the fuel efficiency is improved and the auxiliary machines 32, 33, 34 can be made compact.
